COMBINED REFUSE-DESTRUCTOR AND STEAM-GENERATOR.

SPECIFICATION forming part of Letters Patent No. 658,695, datedSeptember 25, 1900.

Application led December 23, 1897. Serial No. 663,135. (No model.)

To all whom t may concern: are indicated by the same reference-figures,Beit known that we, JOHN THOMAS WOOD and in the case of sections thedirection in and JOHN ALEXANDER BRODIE, subjects of which they areviewed is indicated by the the Queen of Great Britain and Ireland,resmall arrows placed adjacent to the letters 55 5 siding at Liverpool,in the county of Lancasdenoting the plane of section.

This invention relates to combined refusetween two destructor-cells,such as 2 and 2b, destrnctors and steam-generators; and it has so thatin the set there are twice as many defor objects, first, to so arrangethe destrucl structor-cells as steam-generators, and there 65 i5tor-cells and generators that while insuring are between each pair ofsteam-generators, a complete combustion and mixture of the as 1fl and1b, two destructor-cells, as 2b and 2. gases in the former they may beled with as The fire-grates of the steam-generators are little reductionof temperature as possible to preferably arranged, as shown, with thefirethe heating-surfaces of the latter; second, to grates at oppositeends alternately, so that 7o zo arrange the fines of a set ofdestructor-cells the generator 1, whose fire-grate is to the andgenerators so that individual generators right, is supplied with gasesfrom the adjacent or destructor-cells may be taken out of action cells2a and 2b through the passages 3 at the for repair, tbc., and so thatthe cooled gases right-hand side, while the generator 1b, whose may bereduced in Velocityand the deposited fire-grate is to the left, issupplied from the 75 25 dustremoved; third,to providearrangements cell2c and a second cell beyond the limits of for the combustion of coke inthe generators the drawings through the passages 3 at the for auxiliaryheating or to serve as fumeleft-hand side.

The thisinvention. Fig. 2 is avertical transverse space 9 below the trough 6 communicates be- 95 45section through a pair of destructor-cells on low with the common hott1uef10 through a the line A A of Figs. 1 and 4. Fig. 3 is a passage 11,cont-rolled bya damper 12, and it vertical transverse section through asteamalso communicates above with the furnace 4 generator space on theline B B of Figs. 1 through passages 13 at the sidesof the trough and 4,and Fig. '4 is a section on the line C C 6. 3 are passages leadingdirectly from the roo 5o of Figs. 2 and 3. i adjacentdestructor-cells tothe heating-sur- Throughout the drawings the same parts K faces of thesteam-generator, and 14 are passages leading to the common hot iiue 10.24, Fig. 2, are delectors, of refractory material, to preventI as far aspossible the entr \7 of cold air into the passages 3 when the cell-doorsare open, these parts 24 extending inward from a point over thecell-doors sufcently far to deect any cold air that might gain accessthrough said door inward over the grat-es, whereby the cold air will beheated.

With the arrangement described if it bedesired to pass the hot gasesdirectly from the adjacent des! ructor-cells to the steam-generator thedam pers 15 and 12 are placed in the positions indicated in full linesin Figs. Band 4. The gases then flow through the passages 3, circulatearound the heating-surfaces of the steam-generator, are cooled thereby,and then pass through the passage 16 to the comlnon large cold flue 17,where the velocit)1 is so reduced that any dust remaining iu suspensionis deposited before the gases finally pass out of the chimney.

If it be desired to put the steam-generator out of action, it is onlynecessary to keep the damper 12 closed and to turn the dampers 15 intothe position shown in dotted lines in Fig. 4. The gases from theadjacent destructorcells, if they be in action, then pass down thepassages 14 lo the common hot. flue 10 and are available for heatingsome of the remaining generators, If it be desired to heatthesteamgenerator from some of the cells other than those adjacent-to it,the dainpers 15 are turned into the positions shown in dotted lines, andthe corresponding damper l2 is opened. The hot gases thenV fiow from theholl flue 10 into the space 9 up the passages 13 and over the fire-grate5 into the furnace 4, the defiectors 18 being provided to bring thegases into intimate contact with the fuel on the dre-grate. From thefurnace t the gases pass, as before, to the common cold iiue 17 throughthe passage 17.

It will be seen that the arrangement of the common hot flue and passagesenables any generator to be put out of action, the hot gases from itscorresponding cells then entering the common hot flue and so beingdistributed among the remaining steam-generators. In the same Way anyindividual cell may be taken out of action for repair, cleaning, orother purpose.

The independent furnaces'lt may be kept in action contin nously or ascircumstances dictate. They serve the double purpose of acting asfume-cremators and as sources of heat independent of or auxiliary tothat of the destructor-cells.

The arrangement of the alternate generators, as 1b, with their furnaces4, passages 3, 9, 11, 13, and 14 and hot flue 10 is, as already stated,symmetrically similar to that already described, the correspondingparts, where shown, beingindicated by corresponding reference-gures withdashes appended.

19 is a space between the backs of the destructor-cells, which is foundto be of great service for the inspection of the tubes of the generatorsand for the4 removal of the fine dust deposited below the tubes. It isalso useful when the mechanism for operating the tire-bars of the cellsrequires to be at the back thereof and for enabling the steam-jets usedin connection with the air-supply of the cells to be fitted at the backof the cells instead of the front thereof, where they are objectionableon account of the hissing noise they produce. l

The chargngplatform 20 is placed laterally above v the cells, and thestorage and charging trucks 2l and charging-holes 22 are arranged inaccordance with the said other specification hereinbefore referred to,so that the refuse can be tipped from a cart 23 into the trucks andtransferred into the destructorcells` with a minimum of labor.

Although theiuvention has been described with respect to a set of doubleor back-tobacl; destructor-cells, it is clear that it may with equalfacility be adapted toa set of single cells, in which case only a singlecommon hot flue is required.

We are aware that combined refuse-destructor cells andsteam-generatorshave been used prior to our present invention, and,further, that auxiliary furnaces have been fitted to thesteam-generators, the said furnaces being adapted to serve also asfume-cremators, and to such broadly we make no claim.
